  • Big Memory Leak Bug Found In GNOME Shell; Might Remain Unpatched In Ubuntu 18.04

    For now, the users who couldn’t benefit from the patch can restart Gnome Shell after a couple of hours to free up memory. To do this, press Alt + F2. Then type r and press Enter.

  • Continues Integration in Librsvg, Part 1

    Rust makes it trivial to write any kind of tests for your project. But what good are they if you do not run them? In this blog series I am gonna explore the capabilities of Gitlab-CI and document how it is used in Librsvg.

  • Continues Integration in Librsvg, Part 2
  • Continues Integration in Librsvg, Part 3

    Generally 5min/job does not seem like a terribly long time to wait, but it can add up really quickly when you add couple of jobs to the pipeline. First let’s take a look where most of the time is spent. First of jobs currently are spawned in a clean environment, which means each time we want to build the Rust part of librsvg, we download the whole cargo registry and all of the cargo dependencies each time. That’s our first low hanging fruit! Apart from that another side-effect of the clean environment is that we build librsvg from scratch each time, meaning we don’t make use of the incremental compilation that modern compilers offer. So let’s get started.

  • [GNOME] Builder Nightly

    One of the great aspects of the Flatpak model, apart from separating apps from the OS, is that you can have multiple versions of the same app installed concurrently. You can rely on the stable release while trying things out in the development or nightly built version. This creates a need to easily identify the two versions apart when launching it with the shell.

  • SVG Rendering and GSVGtk

    For SVG rendering, we have few options: librsvg, as the most popular one,,and Lasem, maybe others. Both take an SVG file, parse it and render it over specified Cairo.Context.

  • GTask and Threaded Workers

    GTask is super handy, but it’s important you’re very careful with it when threading is involved.

  • gksu is dead. Long live PolicyKit

    Today, gksu was removed from Debian unstable. It was already removed 2 months ago from Debian Testing (which will eventually be released as Debian 10 “Buster”).

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
